## Problem statement

In this challenge, you need to implement sending and displaying a sent email using the MVP pattern. You have already been given the dummy code for the classes you need to implement.

The `Model` class should contain the following:

* The properties: sender's name, receiver's name, and the email title

* The get and set functions to access and set the values of each property

In the `View` class, you need to do the following:

* Define the `sendEmail` function to send an email

In the `Presenter` class, you need to do the following:

* Define the `setModel` function that sets the model

* Define the `getView` function to return the view

* Define the `sendEmail` function that sets the properties of the email and displays the email information

## Input

The `sendEmail` function is called

## Output

The information of the email is displayed 

## Sample input

```
var model   = new Model()
var view = new View()
var presenter = new Presenter(view)
presenter.setModel(model)
view.registerWith(presenter)
presenter.getView().sendEmail("Rachel", "Joey", "Rent Discussion")
presenter.getView().sendEmail("Monica", "Phoebe", "Smelly Cat Draft")
```

## Sample output

```
"Email From: Joey To: Rachel Title: Rent Discussion"

"Email From: Phoebe To: Monica Title: Smelly Cat Draft"
```
